Application filed November 19, 1915. Serial No. 62,389.

To all "whom it may concern:

Be it known that I, JOHN T. THOMAS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Anticreeping Appln ances, of which the following is a specification.

My invention relates to anticreeping devices for railway rails, and my object is to provide a simple and efficient device of this character embodying a tapered lock member adapted to firmly engage the adjacent side of a rail and prevent the same from creep ing longitudinally.

The device further embodies means for abutting two adjacent ties, thereby enabling said device to effectually hold the rail from creeping in either direction.

In the accompanying drawings which illustrate the invention:

Figure 1 is a broken plan View of a rail and two cross-ties with my device applied thereto.

Fig. 2 is a vertical cross section on line 11-11 of Fig. 1.

Fig. 3 is a broken side elevation of the rail and the cross-ties, with my device applied thereto.

Fig. & is a detail section on line IV-IV of Fig. 1.

Fig. 5 is a detail of a tapered lock member constltuting an important feature of 4 the invention.

Fig. 6 is a broken plan view of a rail and a cross-tie with a modified form of the device applied thereto.

Fig. 7 is a cross section on line VIL-VII of Fig. 6.

Fig. 9 is a detall of the modified form of tapered lock member.

A designates the rail and B and C two cross-ties extending beneath said rail.

1 designates my device which embodies a plate 2 having abutments 3 and 4c, extending in opposite directions to each other and at substantially rightangles to said plate. The vertical faces at the ends of the abutments 3 and 1 have teeth 5 and 6, adapted to become embedded in the adjacent sides of the cross-ties B and C, respectively, and thus prevent said faces from slipping out of position on the ties.

One side of the plate 2 has a lip 7 adapted to snugly embrace the adjacent rail base flange D,.while the opposite side of the plate 2 has a lip 8 extending beyond and above the edge of the adjacent rail base flange D, as disclosed by Fig. 2. By thus spacing the lip S from the adjacent rail base flange D,'the device can be readily applied to and removed from the rail by proper manipulation of the plate 2. The space between the lip 8 and the adjacent rail base flange D, also admits of a tapered lock member 9, whereby the device is firmly secured to the rail.

The tapered lock member 9 has a beveled side 10 to fit the corresponding interior wall of the lip 8, while its opposite side has flanges 11- and 12, to overlap and underlap the adjacent rail base flange D (Fig. 2). The plate2 has an off-set 13, adjacent the lip 8, to receive the bottom of the tapered member 9, which has a longitudinal ballway 1.4., registering with a transverse ballway in said lip 8. The bottom of the ballway 14: is inclined as indicated at 16, while the top of the ballway 15 is inclined as indicated at 17, the pitch of the incline 17 being greater than the pitch of the incline 16, (Fig. at) to check the'downward movement of a ball 18, located in the ballways 14: and 15.

The upper end of the ballway 15 communicates with a recess 19, of sufficient size to receive the ball 18, where said ball may be retained by a pin introduced through holes when it is desired to insert or remove the tapered member 9 from operative position. The lower end of the ballway M is partly closed by shoulders 21..to prevent the ball 18 from running out through said end.

In practice, after the plate 2 has been applied transversely to the underside of the rail as indicated by Fig. 1, with the abutments 3 and 4 bearing against the cross-ties B and C, respectively. the device is firmly held in place by forcing the tapered lock member 9 into its effective position, which operation firmly draws the lip 7 into engagement with the adjacent rail base D.

The temporary pin support for the ball 18 is then removed to permit the latter to fall from the recess 19 and roll down the ballway 14; until it impinges against the top of the ballway 15, and secures the tapered lock member 9 in place. iVhen it is desired to remove the tapered lock member 9, the ball is released therefrom by a pin or punch inserted between the shoulders 21. Any tendency of the rail to creep in the direction of the arrow at is effectually overcome by the abutment 3 bearing against the cross-tie B, and any tendency of the rail to creep in an opposite direction is overcome by the abutment 4 bearing against the cross-tie C.

In the modified form disclosed by Figs. 6 to 9, inclusive, the construction and application are practically the same as in the preferred form, except that the abutnients 3 and I are dispensed with and one side of the tapered member 9' has an abutment 3 to bear against one of the cross-ties.

Like parts of the modified form have the same numerals with exponents, as similar parts of the preferred form, so that further description thereof is deemed unnecessary.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. I11 an appliance of the character described, a plate adapted to extend beneath a rail, lips at the ends of said plate to overlap the rail base flanges, means interposed between one of said lips and the adjacent rail base flange to firmly grip the same, and means extending from the plate to abut two adjacent cross-ties underlying the rail.

2. In an appliance of the character described, a. plate adapted to extend beneath a rail, a lip at one end of said plate to snugly embrace the adjacent rail base flange, a lip at the opposite end of said plate spaced from the adjacent rail base flange, means interposed between the last-mentioned lip and the adjacent rail base flange to firmly engage the same, and abntments projectingin opposite directions from the plate to bear against two cross-ties underlying the rail.

3. In an appliance of the character described, a plate adapted to extend beneath a rail, means on said plate to lap the rail base flanges, a tapered lock member adapted to be interposed between one of said means and the adjacent rail base flange to firmly engage the same, and a ball for securing said tapered lock member in position.

4. In appliance of the character described, a plate adapted to extend beneath a rail, means on said plate to lap the rail base flanges, one of said means having a hallway therein, a tapered lock member adapted to be interposed between one of said means and the adjacent rail base flange to firmly engage the same, and a ball interposed between the ballway and said tapered lock member.

5. In an appliance of the character described, a plate adapted to extend transversely beneath a rail, means on'said plate to lap the rail base flanges, a tapered lock member adapted to be interposed between one of said means and the adjacent rail base flange to firmly engage the same, said tapered lock member having a hallway there in, and a ball in said hallway adapted to lock said tapered lock member in position.

In testimony whereof I affix my signature, in the presence of two witnesses.
